基于“知识导图”,提升初中科学章节复习实效性的研究

Research on Improving the Effectiveness of Junior High School Science Chapter Review Based on"Knowledge Map"

及时有效的复习,是对知识的升华。及时进行章节知识梳理,对学生来说非常有必要。为避免把章节复习变成简单的"炒冷饭",笔者在教学中,以编写章节"知识导图"为载体,提升章节复习的实效性。"知识导图"是将概念图、知识摘要和典题赏析三个板块呈现在一张8K的纸上。概念图要做到提纲挈领重脉络梳理。知识摘要要根据知识点的难易程度,采用不同的复习策略。典题赏析板块力求精选题目深度剖析。

Timely and effective review is the sublimation of knowledge.It is very necessary for students to sort out the chapter knowledge in time.In order to avoid the chapter review into a simple"fried rice",the author,in teaching,takes the compilation of chapter"knowledge map"as the carrier to improve the effectiveness of chapter review."Knowledge map"is to present the concept map,knowledge summary and appreciation of classic questions on a piece of 8K paper.The concept map should be focused on the outline and the context.According to the difficulty of knowledge points,different review strategies should be adopted.The appreciation section of classical questions strives to select topics for in-depth analysis.
